Summary
Pulls real-time weather data from the National Weather Service API with two focused tools: get_alerts fetches active alerts by state code, and get_forecast grabs the next five forecast periods for any lat/long point in the US. Reach for this when you need Claude to check current weather warnings or pull a quick forecast without leaving the conversation. It's a thin wrapper over api.weather.gov, so you get official NWS data with minimal overhead. Install via pip, run the stdio transport, and point your MCP client at the Python module. No API keys needed since it uses public NOAA endpoints.

Publishing Steps (Overview)
- Authenticate with publisher (GitHub namespace):
mcp-publisher login github - Create and push repo to GitHub (see steps below).
- (Optional) Publish to PyPI if distributing as a package.
- Publish to MCP registry:
mcp-publisher publish - Verify:
curl "https://registry.modelcontextprotocol.io/v0/servers?search=io.github.vtiwari/weather-mcp"
Create & Push GitHub Repository
If this directory is not yet a git repo:
git init
git add .
git commit -m "Initial commit: Weather MCP server"
Create repo (GitHub CLI) and push:
gh repo create vtiwari/weather-mcp --public --source . --remote origin --push
If not using GitHub CLI, create the repo manually via the GitHub web UI, then:
git remote add origin https://github.com/vtiwari/weather-mcp.git
git branch -M main
git push -u origin main
Tag version for release consistency:
git tag v0.1.0
